Highest temperature in Munich on August 10?

Platform comparison

Market context

Munich’s temperature profile has not shifted enough in the last 24–48 hours to suggest a dramatic move away from a late-summer outcome: August there is usually warm, with typical daily highs around 24°C and record highs in the high 30s, so the market’s 1% **YES** price is still anchored to a fairly normal climatology rather than an anomalous setup.[1][17] For this contract, the key number is the highest reading in Weather Underground’s Daily Observations table for Munich Airport Station, not the headline day-high figure, so any trader reading the forecast should watch the intraday observations rather than the summary box.[3]

History argues that outsized heat is possible but uncommon. Munich’s August record high is 37.0°C, and the 10 August record shown in one climatology source is 35.9°C, which means a very hot day is not impossible but would require a sharp short-term warm spell well above the month’s average profile.[1][5] More recent August histories also show plenty of middling outcomes in the low-to-mid 20s Celsius, with occasional spikes into the high 20s and low 30s, which is closer to the centre of the distribution than the record end.[8][13]

The main catalysts are the day-of forecast evolution, cloud cover, precipitation timing, and wind direction, because these can materially cap or enhance the afternoon maximum at Munich Airport. AccuWeather’s current Munich outlook already points to a forecast high near 92°F/33°C for 10 August, which is warm enough to keep higher temperature buckets live if the forecast verifies, but the final settlement will depend on the actual observation window rather than the forecast headline.[2] Traders should also watch whether any showers or frontal passage arrive during the warming peak, since the market settles at 12:00 UTC and the day’s high can be set before or after that cutoff depending on how the weather develops.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
